[issue21165] Optimize str.translate() for replacement with substrings and non-ASCII strings

[STINNER Victor]

STINNER Victor added the comment:

codecs.charmap_build() (PyUnicode_BuildEncodingMap()) creates a C array ("a three-level trie") for fast lookup. It is used with codecs.charmap_encode() for 8-bit encodings. We may reuse it.
